题目：Scientific and technological advances have changed our lives. But some scientists in some fields say that scientists are not able to find solutions to the problems they have created. To what extent do you agree or disagree?
范文：We sure live differently from our parents did decades ago. The changes are wide and profound. At the same time, we are facing challenges and problems unknown in the past. Could we find solutions to problems created by scientific development? The answer seems to be no.
Some of the most obvious problems caused by technological advances lie in the IT industry. At a time when we did not have computers and electronic bank services, people took money with them and paid by cash. If they were stolen, only the amount they had with them was lost. But now credit cards are more commonly used in shopping malls and other places, crimes again us have become more serious and caused greater losses to people. A thief may tape the code of your credit card and make a copy of it. Then he could safely withdraw all your money from an ATM machine. Crimes such as this are very sticky to solve because there is no witness and the surveillance cameras give little help to the police.
Another example is the issue of information control with the media industry including TV networks and Internet that give easy access to information without discrimination to people’s age. This has created a huge problem for parents and schools because teenage people are particularly vulnerable to adult materials and information violent in nature. In the past, when most information came in the form of print, it was relatively easy to control what children read. When a parent put away a book unsuitable for children, they were cut off from the source of information. With
computer parents could use software to filter bad web sites but could not prevent new ones from appearing every day.
People are working very hard to solve such problems that come along with advances in science and technology, but the efforts are not sufficient and not very successful. Even with the little progress we have achieved, we find ourselves defeated by new problems with greater complexity and in wider scope.
In conclusion, developments in many fields of our life have brought us both benefits and problems. Developments in the banking industry give us greater convenience but making us targets of computer-based theft. Changes in media industry expose young people to inappropriate information difficult for parent’s control. However up until now, we have not successfully found permanent solutions yet.
Mobile (cell) phones and the Internet play an important role in the way in whichpeople relate to one another socially. Is this a positive or negative development? What is your opinion?
Give reasons for your answer and include any relevant examples from your own knowledge or experience.
Now that you are benefitting from the use of the mobile phone and the Internetas social media as well as social interaction, could you imagine what your daily liveswould be like without these inventions ? Living in this age of information technology may be a blessing, but there seems an undesirable feeling under disguise. For that matter, probably what you like would be social connectivity and what you dislike might be personal anxiety.
It is a positive development that people have found it so easy to relate to one another electronically and share instantly in the social context. As technology has advanced, so has the need to remain contact with friends, family and loved ones. Through digital networking, the cell phone and the Internet have opened doors to the current generation's lives, as previously unheard of. While it goes without saying themany benefits that the Internet has to offer, the latest hand phones are well-equipped with high end features catering to a variety of communication needs from voice calls to text messaging. Apart from being able to help connect people anywhere andanytime, new handsets of innovative technology boast cutting-edge functions
designed to upgrade work performance and provide fun factors, all at your fingertips.Besides, what do you have to say about Facebook, Twitter and Google+ that are out there on your computer screens or on your smart phones?
Nevertheless, the heavy use in social networking of the mobile phone and the Internet causes anxiety, not to mention the negative effects produced by possible radiation. Chances are that these gadgets are getting you on nerves. It is not so much because of such networking devices keeping you on alert 24/7 as because of the
thought of being without them sometimes. So, there are feelings of increased anxiety during the absence of social mobility, as if when you were psychologically alone in the
middle of nowhere. And yet, once people being connected, it appears to be no end of interactive communication, particularly when driving, for instance. In this case, the epidemic of people using cell phones to talk and to send text messages via the Internet behind the wheel could give rise to more of a hazard than drunk driving.
As long as social interaction is concerned, it may be said that the hi-tech mobility is like a useful gift from heaven rather than a psychological disease from hell. The benefits of social interaction through the cellular and the Wi-fi seem indeed too good to be blamed. Whatever, there is no turning back to the age of B.C. (BeforeComputer).
